Referring to the draw the breech-piece, which has hex which is pivotedto'said-part and=4 ithe Adlfof It part/sare capable ofsliding@,olla-r1d'frlongitiidina channeled-part 5 ofthe h dle-or'sto vofthe hammer andas extending over the spur or lug 6b .on the' hammervside, with which its notches are intended to engage to retain the hammer1n full or half-cocked positions, as best shown in Fig. 2. The free.endof the sear extends forwardly ofthe 'the trigger 7 is provided witha safety-finger 10, 'which 'is pivoted at its lower end to the. rear ofthe trigger-head, as shown, and eX- tends upwardlytherefrom to the rearof the spur or projection 9 of thesear with which it is normally held inengagement byl the action thereon of a coiled spring l0', ,which iscarried within a socket in the trigger-head, as shown.in Figs. land 6.The finger 10 is provided on its `forward surface with a tooth 10, whichis intended to engage and lift the sear from engagement with the hammerlug 6b at a` predetermined point in the pulling movement of the trigger,and has sits upper end projected in position to be engaged by thebreech-piece 1 and moved out of coacting relation with the sear on there'rwardmovement of th`e breechpiece, as shown in 'F ig. 10, thuspreventing a release bf the hammer from cocked position until thesliding parts have returned to their'normal forward position andthecylinder 4 llas been rotated to place the next cartridge in position fortiring. It is thus apparent that the finger 10 serves as an intermediarybetween the trigger and Sear and only stands in position to trip thesear on a pulling of the trigger when the sliding parts 'are in normalor firing position.

The sliding-parts have their forward movement limited by the stop-piece11, which Vis pivoted to the stock part 5', as at 11, and

has its ^`forward end turned upward in the path otmovement of the boss22L at the forward end of the part 2 of the breech-piece. The side edgesof said upwardly turned portionare bent around the opposite sides of thestock part 5 to form finger-grips to facilitate a lowering of thestop-piece against the tension of the compression- Spring 12 vwhen it isdesired to remove the` sliding-parts from the stock, as shown in Fig. 2.The stop-piece 11 has an inturned lip. 13 at its upper end adapted-toproject within a groove 13 in the end of the boss 2a to prevent alowering of the stop-piece except when the sliding-parts are moved rear`wardly from normal position to disengage said lip and groove.

The "slidinff-parts are normally held at their'lmit ofD forward movementby the acl which is carried`=by a pin 15 projecting rear- 'tion 'ofthe,coiled compressioli-spring 14,

and t'he'triggerto yieldingly maintain them in normal positions, asshown.

To adapt the-revolver to automatically repeat its tire until all ofthecartridges in th'e'cylinder have been discharged, I pivot a llever 16within the stock part 5 to 011e side thereof, as at 17 (see Figs.2 and11), and j have its rear 'end terminating beneath the forward end of theseal' 9 in contiguous position thereto and its forward end terminatingadjacent to the forward end of the stock Vpart 5 and turned upas shownat 16. Carried within the stock 5 by a pivot or pin 18,

which movably projects through a slot 19 in the stock nside and carriesa thumb-button 20 at its outer end, (see Fig. 8), is a finger 21, whichhas its forward end tapered and resting on the rear end of the lever 16.lVhen the button 20 is pushed forward the nose or tapered end of thefinger21 is intended to Work between the rear end of the lever 16 andthe sear end and effect a raising of the forward end of the lever sothat its 'upturned end stands in the path of movement of the lug 2bwhich is formed on the contiguous side of the boss 2 on the lbreechpart2. It is thus apparent that on the return of the sliding-parts to theirnormal forward positions after a recoil, the lug 2b engages and forcesthe upturned end of the lever 16 down and eects a consequent raising ofthe rear end ofthe lever, which acts on the sear through the interposedend of the linger 21 to release the same from engagement with the hammerand permit a discharge of the next cartridge in the cylinder. The recoilof the sliding-parts from i this discharge recocks the liammer,.which isagam released 1n the same n'taypasbefore as soon as the sliding-partsreturn to ,their normal forward positions, thus causing the discharge ofthe cartridges in the cylinder to be automatically repeated with greatrapidity. y

Projecting upward y from one side of the trigger-head in advance of itspivot is a finger 22, the nose of which, whenV both the breech-part 2;and the trigger are in normal positions, is intended to stand inposition to engage the shoulder 23 on the contiguous side of thebreech-part 2 to prevent a rearward movement ofthe sliding-parts untilthe trigger has been pulled suilicienlly to draw the finger down out ofengaging position with said shoulder. Vith this form of lock it ispossible to stop'the automatic repeating of the fire at any time bysimply releasing the trigger to permit it to return to normal position.

The cylinder 4 is caused to partially rotate at each recoil movement ofthe sliding- Wardly from the boss 2a on the breech Yevtension part 2 andhas its rear end in abutment with a lug 7a on the triggertop, thus`adapting it to act both on the sliding-parts parts to succesf-ivelylmove the chambers thereof in register with the barrel, due to a, zig-zaggroove formed circumferentially thereon working over a pin 24,' which isposedportions 27, which successively con- Iicttlieopposite'ends of theportions 27, as

shown. The portions. 27 are equal in length 'to thereeoilfmovementjofthe slidingl parts,

and ,have their bottoms forwardly inclined and terminating-in abruptdepressions 'which form "the Ishoulders 27EL lin the planes 'of therear,- walls of the diagonal portions; 27. It

' is' thusk apparent that on 'the rearward movement of the sliding-partsthe pin 24 will be depressedby fthe incline of the associated Way 27 to,permititto passl over-the shoulder gammer 6 on the pivot thereof and'has its' .50

27a, and at the' limit of such rearward movement Willbe forced outwardlyby the action4 of its spring Iinto the' associatedway 27 in vabutmentwith said shoulder, so that on the forwardmovement' of the sliding partsthe ,cylinder will be constrained to turnv due to fthefcpe'ratingi-ation of thepin and diagonal way 27 Y lnFigs, 2`andj10, 28designates a roller,

wardly entende'dsides l of the breech-piece andf intended 'to' .coact.with the forward Sand 1'0. The lowerend ofthe plate is'pro-l vided witha spring-catch 32, vthe outer end [of which is intended to engage aregistering depression-in the stock end. To facilitate a removal of theplate from the stock, an external spring-button 33.is providedat thebase of the depression and 1s adapted to be ,pressed to eii'ect acompression of the catch 32 against the tension of its spring.

-In Figs.

iece, which iscarried at the side of the earwend turned to engage theback of the jhamx'ner to limit the relative pivotal movement thereof.The forward end of the tumbler is extended in position to coact with theunder sideof the tail-piece 7 of the trigger,

,as shown in Fig. 1, whereby-to cause a cock.- ing movement of thehammer to move the trigger on its' pivot so that when .r the hammeri'sin full cocked position thetrigger will have-a fixed pullingAposition dilierent `from its .nor'mal position, thus shortening thelength of pull of theI trigger to release thefsear and making a rapidfiring possible. 35 designates an adjustable stoppin for `themain-spring 8'. The inner end of this pi'n is in abutment with the freeend of the `1 and 10, 34 designates a tumbler spring and its outer endis threaded through the rear wall of the. stock toenable the spring'tobe adjusted relativetothe hammer as `the rebound of the' hammertosafety- 'cocked position may require, or in other words v,it isnecessary 'to adjust'thespringstop softhat thespring-tension ivill'notbe -brought-to bear on `the-hammer until it has rebounded tosafety-cocked position.

In practice therevolver embodying -my pullingthe trigger to ycause thetail-piece7 thereofA to act on vthe hammer-piece Ga; to

which point-the tail-piece 7 releases the hammer-piece 6a to permit thedischarge, as in the self-cooking revolver.' On the recoil of thesliding parts, occasioned bythe discharge, the hammer 6 is automaticallyrecoclred and the safety-linger l0. movedv out 'of engagement-with thesear 9 to prevent a release vof the hammeruntil the .slidingparts havereturned to their normal positions.y On the recoil and forwardn-.ovements of the sliding-parts thefcylinder 4 is also rotated to bringthe next cartridge in position to be fired, due to the `.coperatingaction of the yielding pin 2-landy cylinder groove, as. 'above'described. Should the thumb-button 20 and' its attached finger vil bein'rearward position vthe fire-will not be repeated until the trigger ispulled to release the sear' from the hammeigbut should"said thumb-buttonand finger be in forward posi= tion the lug 2a on the vbreechpartv2 willcoactwith the uptur'ned'end 16 ofthe lever I6 at the limitj of forwardmovement of the sliding-parts, after a recoil action' thereof, andetfect an automatic'rele'ase'of the sear from the hammer,-thus 'causingthe lire to be repeated as many times as there are cartridges in thecylinder, provided, of course, the trigger is maintained in pulledposition. Should the trigger be released the tiring will be stopped dueto the nose of the llinger Z2 thereon engaging 'the shoulder 23 on thebreech-part 2 toA prevent a recoil movement of the sliding-parts. The.sliding-parts may stock by bneakmg the breech, bar-rel and cylindergroove from engagement with the down to permit the sliding-parts to bedrawnoutwardly from* the stock part 5', as shown in Fig.v 2.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is,-

'1. Ina recoil ire-arm,the combination of the stock,a recoil part, asear, a member disposed longitudinally of the stock'and pivoted thereto,said member 'having one end disposed to coact with and be moved by therecoil part at a predetermined polntnin its raise` the hammer to cockedposition at- -invention-is tired inthe first instance by be easily andquickly removed from the' cylinder. in the usual manner to release thepin 24, and then drawing the stop-piecell' with the sliding breech-part,the stock, and' the sear, of a lever pivoted tothe stock in reclininerposition beneath. the sliding breechpart and having its forward endfashioned to be engaged and'moved by a coperating portion of thebreech-part at a predetermined point in its sliding movements and its.rear end positioned adjacent the Sear, and means actuated by a 4movementof said lever to impart a releasing movement to the Sear.

4. In a recoil lire-arm, the combination with the sliding breech-partand. the Sear, of a lever adapted to be moved by said breechpart at apredetermined point in its sliding movements and having `its rear enddisposed in contiguous position to the scar, and a manually controlledmember adapted to be moved intermediate the sear andrear end of I thelever to communicate a releasing moveman of the guide to coach with oneof the recoil parts to limit the, forward movement of said partsrelative to the; ide: and provided with'an'inturned lip W ich coacts;with one of the recoil parts to prevent. a. movement 45 of the member onits pivot to permit a withdrawal of the recoil parts from the guidee'xcept when the recoil parts are moved slightly rearwardly from normalpo sition.

6..In a recoil re-arm, the combination with the sliding 'recoil partsand the stock guide therefore, of an L-sha edmember pivoted to the stockguide'an v'htinally serving as a stop for limiting the rblntivemovements of the recoil parts and ,guide in one direction and coperatingwith one of the recoil parts when both said parts and the. member are innormal A positions whereby to. prevent a releasing movement of themember to permit a withdrawal of the recoil parts from the guide.

7 In a fire-arm, the combination ,with they hammer and trigger, saidtrigger having a tail-piece, of a tumbler-piece carried at the side ofthe hammer on the pivot thereof and 'having its rear endbent to therear'of the hammer to limit the relative movements thereof and its forwardend projected in positiontoengage the under side of the triggertail-pieceto effect a pullingmovement of the trigger when the hammer iscocked.

' In test mony whereof I have vhereunto signed my name to thisspecification in the presence of two subscribing witnesses.
